[PATCH] D38954: [Sema] -Wzero-as-null-pointer-constant: don't warn for system macros other than NULL.

[Roman Lebedev via Phabricator via cfe-commits]

lebedev.ri updated this revision to Diff 120316.
lebedev.ri added a comment.

Add `Diags.isIgnored()` early return + move `C++11` early return earlier too.
At least partially should help avoid the penalty of `findMacroSpelling()`
I don't think i see any way to avoid `findMacroSpelling()` :/
